Robert Lieutenant Dale is not a well-documented historical figure within the art historical record, and as such, there is no comprehensive biography available for him. It is possible that the name provided might be subject to misspelling, confusion with a person from a different field, or simply not widely recognized in the realm of art history. If Robert Lieutenant Dale was an artist, he may have been a minor or local figure, and thus not widely noted in art historical texts or databases. Without specific details such as birthplace, style of art, medium, or any notable works, it is challenging to provide an accurate and detailed biography. If you have more information or context regarding Robert Lieutenant Dale's contributions to art or any specific time period or region with which he may have been associated, please provide it, and I can attempt to offer a more detailed response.
